ADHESIVE-APPLYING APPARATUS.

Specification of Letters Patent.

. Patented Aug. 8, 1911.

Application filed February 8, 1909. Serial No. 476,706.

T all whoa/mi. may conce n:

Be it known that IylVrnmnu LINDEN- FELSER, a citizen of the UnitedStates, and a resident of Ozone Park, borough of Queens, city of NewYork, in the county of Queens and State of New York, have inventedcertain new and useful Improvevarious parts are readily accessible, andthe adhesive supplying surface removable.

The nature of my invention will be best understood in connection withthe accompanying drawingstin which- Figure 1 is a front elevation of theimproved apparatus with a portion of the mechanism broken away. i Fig. 2is a side elevation. a detail view illustratin the action of theapparatus.

Similar characters of reference designate corresponding parts throughoutthe several views,

Referring now to the drawings. designates a supporting frame 111 whichis cast an adhesive container 11 0 on at. the top.

except at the front where i' is closed by a" feed plate 12. The sides ofthe container 11 are notched to receive a shaft- 13 carrying theadhesive supplying roll 14 which dips into said container. A wipingplate 15' is suitably supported Within said container to remove thesuperfluous adhesive from the roll 14.

Upon the shaft 13 is mounted a driving gear 16 adapted to be rotated bya crank 17, and is locked against return movement by a spring pressedpawl 18. Pivotally connected to the sides of the frame 10, at one end,are two upright plates 19 of a casing (amtaining, the paper feeding andtake-off mechanism. This'casing is adapted to fit upon the top of theframe 10, andmay be locked to the sides of same by means of suitablehooks 20. i

Shafts 21, 22, and 23 are supported by the plates 19 and carrycorresponding rolls 24, 25 and .26, as well as gear wheels 27-, 28

| l l I i l has been exposed and 29. The bearings of these shafts may beslotted to allow for various thickness of paper. A rod 30 is alsomounted in these plates and carries a number of fingers 31 which rest atvarious points along the surface of the adhesive supplying roll 1%, therequired pressure being provided by means of a spring 32 acting upon therod 30. These fingers are shaped to direct the paper 33 in the properdirection, as will hereinafter be more fully explained.

A number of transverse grooves 34 are cut. into the roll and the roll"26 is provided with a number of friction disks 35 adapted to registerwith the said grooves 34.

The operation of my apparatus is as follows: The paper 33 is placed uponthe feed plate 12 and brought under the roll 24. In turning the crankt7. the surface of the adhesive supplying roll 14 carries suliicientadhesive up from the container 11, and ro- -tates the said roll 24,through gear wheels 16 and '27. the two rolls (o-acting to feed thepaper 2323 forward and at the same time to force it against the adhesivecoated surface of the roll H. thereby coating the said paper. By thetime the paper strikes the roll '25. which is likewise driven from roll14, through gears 16 and 28. it has a tendency to curl backwardly due tothe moisturereceived fr'om the adhesive, and is assisted in its removalby the motion of the said roll 25 as well as by the fingers 31. Thesefingers lift the same from off the surface of the roll 14. and guide anddirect it between the roll and the take-off roll 26 whose friction disks35 make contact with the said paper. tending to forcibly withdraw itfrom the surface of the roll 14.

As the frictioddisks 35 come in contact with the coated snrface'of thepaper, which to the adhesive, they noturally will retain some of saidadhesive. This adhesive, however, is not communicated to the roll 25,and thereby to the unexposed side of subsequent. papers, since thegrooves 34 are provided, and register with the said friction disks If itbe desired to remove the adhesive from the container 11. as well as toclean the roll 14 and other parts of the mechanism, the entire upperratus may be lifted off by unhooking the hooks 20, whereupon the roll 14may be lifted out and the container 11 will be readilv accessible.
